In order to study children's strategies for solving geometric matrices similar to those in the Raven's Progressive Matrices, ninety 7-, 10-, and 13-year-old boys and girls were administered tests of auditory and visual memory, the Raven's, and geometric matrices. The matrices varied in number of elements (1 to 3) and number of transformations (0 to 2). The fact that the 10- and 13-year-olds increased their latency to solution with increased item complexity on correctly completed matrices suggests support for a two-component process of identification of elements and specification and execution of transformations. However, high error rates for all ages on one particular item type for incorrectly completed matrices suggested strategies which focused on specifying transformations to the exclusion of identifying elements or executing transformations. Solution of figural matrices for 10- and 13-year-olds appeared to place demands on both visual and auditory memory. (Author/MP)
